<h3>Background</h3> Falls represent a major health problem for older adults and often lead to disability and mortality. Each year 30% to 50% of community-dwelling older adults report a fall and almost 75% of falls occur in bedrooms or bathrooms, and 41% of all falls occur during transfers [1,2]. Patients with hip osteoarthritis (OA) have many hip and age-related dysfunctions including muscle weakness, sensory loss, gait and balance deficits, which all increase the risk of falls [3]. Task-specificity has been shown to be a critical factor in the effectiveness of fall-reducing interventions [4]. The Lie-to-Sit-to-Stand-to-Walk Transfer Test (LSSWT) was created to measure complicated transfer abilities in older people [5]. However, the LSSWT's reliability and validity are not known in patients with hip OA. <h3>Objectives</h3> The aim of this study was to investigate the reliability, validity, and minimal clinically important difference (MCID) of the LSSWT in patients with hip OA. <h3>Methods</h3> Twenty-seven patients with hip OA were included in this study. Patients performed trials for the LSSWT and the Timed up-and-go (TUG) test. Between the trials, patients rested for an hour to prevent fatigue. <h3>Results</h3> The relative (ICC coefficient) and absolute (SEM and SRD95) reliability of the LSSWT were 0.95, 0.49, and 1,35 respectively. The Pearson correlation coefficient between the LSSWT and the TUG was 0.69. <h3>Conclusion</h3> The analysis showed that the LSSWT has excellent reliability and high validity in hip OA. (p&lt;0.001). The low MCID of the LSSWT (1.35) shows its sensitivity and can be used as a responsive outcome measure of interventions and fall risk. the LSSWT also can be valuable in determining independent transferring ability, admissions, or discharges from/to healthcare/residential facilities. <h3>References</h3> [1]Johnson EG, Meltzer JD.
